To all whom t .may con/cern..-

Be it known that I, ARNOLD Sruoici, a resi- A dent of Allegheny, in the county of Allegheny act description thereof.

and State of Pennsylvania, have invented av new. and useful-Improvement in Side Bearings for Railway-Cars; and l do hereby declare the follgwing to be a full, clear, and eX- This invention relates to side bearings for railway-cars, such as are used either on the truck-holsters or body-holsters, and especially to side bearings of the frictionless type.

The object of the invention is to provide a side bearing which is constructed in a compact mannercand so that no friction will take place, due to relative movement between the truck. and car-body.

Another object is to provide a side bearing of this type which always presents a frictionless surface for the contact ofthe other vmeinber ofthe car no matter tov what extent the bearing may have been rotated.

To the accomplishment of the aforesaid objects the invention consists of a side bearing provided with antifriction-rollers and arranged in the manner hereinafter described and claimed. i

.ln the accompanying drawings, Figure 1 is a plan view of the bearing. Fig. 2 isan end view ofthe same." Fig. 3 is a cross-section on the line 3 3, Fig. 1 g and Fig. 4 is a vertical lon.- gitudinal section on the line 4 4, Fig. 1.

The bearing comprises a suitable housing or support 1, provided with a base 2 for securing to the truck or body bolster, as the case may b e, and having rising from the base the bearing-standards 3, wlr 'ch are provided with openings 4 for receiving an.y axle 5. The standards are widened out at the openings 4 on the si de which takesy the strain or thrust, as shown at 6, this giving a strong Awide resisting-bearing for the axle 5. The axle is held against endwise displacement by means of suitable pins 7, such as spring cotter-pins, driven through openings in the ends of the axle outside of the bearings 3. Thebends of these pins project beyond the axle and are inpositioii to contact with the shoulder S, formed by the edge of the projecting bearing 6. a consequence the axle is 'not only held against endwise displacement, but also against rotation, so that no wear between the axle and .its bearings can taire place.

' Surrounding the axle are a series of antivfriction-rollers 10, which. contact with the axle in the well-known manner to reduce friction.v These rollers are held "spaced apart' equal distances, so as to prevent their bunching and creating friction one on the other, by

means of suitable spacing-rings 11, which have notched or cut-out portions 12 on their inner, edges which embrace Athe ends of the rollers. `The rollers and spacing-rings are held between the side bearings or standards 3, and therefore are prevented from becoming displaced..

1f desired, the car-bodyor truck, nas the case may be, may contact directly with the rollers 10. I prefer, however, to surroun these rollers by means of a sleeve or hollow cylinder 14, which runs loosely on the rollers. This sleeve or cylinder is recessed at its ends, as at 15, to receive the spacing-rings 11.

The side bearing described is simple of construction, compact, and'strong. The bearing or contact face thereof is cylindrical, and therefore is always in proper position no matter to what extent it may have been turned or rotated. will merely run around loosely onthe rollers 10, the latter in turn running around on the stationary axle 5. As a consequence the side bearing is practically frictionless and also practically free from wear.

It is obvious that this bearing may be used either on the truck or on the car-body with equally good results.4 it is also obvious that variations can be made in the 1; r()portion an arrangement of parts without departing from the spirit of the invention. l/Vhile l prefer to use the sleeve 14, this is not absolutely necessary, as the rollers themselves could be made of suil'ieient diameter to project beyond the bearings or housings, so that the other ineinber of the car can contact directly therewith or the shoe of the matching side bearing could be made suliiciently narrow to pass down-between the bearings and contact lwith the rollers. lt would also be possible to use a number of short sleeves in place of the one ln action the sleeve 14 p 1. A side bearing'for railway-cars comprisv ing a suitable base or bearing providing standards or side walls, an axle mounted in said standards and held against rotation, rollers surrounding said axle and contacting therewith and having unreduoed end ortions, spacing-rings surrounding the en s of the rollers and provided With recesses on their inner edges 'which embrace said rollers', said rollers and spacing-rings being oonned between the. standards of the bearing, and a sleeve surrounding said rollers.

3. A side bearing for railway-oars comprising a base provided with standards having openings therein, an axle mounted in said o eni11gsthe Walls at said openings on the tlrust side being broadened, a pin passing through said axle with its ends rojeeting beyond the same to Contact wit said. broad` ened bearing, a series oli-rollers surrounding' said axleand contacting therewith, e sleeve surrounding said rollers and provided with seriele recessed ends, and spaoing-rings s( said reeessed ends and embracing the emr. said rollers. Aside bearing iormilwejrars compris ing a base, standards rising therefrom end provided With openings, standards being; broadened or widened the thrust side of the openingaan axle rnoui'ited 'in said openings, a pin passing through said. axle and hsving an end in position to Contact with the broadened bearing, a series of rollersy enrrounding said axle, a spacing member for keeping said rollers from contacting with eaoh other, and a sleeve surrounding seid rollers,

In testimony whereof I, the said Aaiei'oLn STUCKI; have hereunt set my hand,
